HARROW AND SEEDER.

SPECIFICATION forming part of Letters Patent No. 552,822, dated January'7, 1896.

Application filed March 5, 1895. Serial No. 540,645. (No model.)

To all who???) it may concern.-

Be it known that I, ELI J. COLBY, a citizen of the United States,residing at Spring Valley, in the county of Fillmore, State ofMinnesota, have invented certain new and useful Improvements in Seedersand Planters, of which the following is a description, reference beinghad to the accompanying drawings, and to the letters and figures ofreference marked thereon.

My invention relates to seeders and planters, and more particularly toan attachment for a harrow, my object being to so construct aseed-distributer that it can be readily applied to any barrow ofordinary form.

The invention is illustrated in the accompanying drawings, in whichFigure l is a top plan View of a harrow with my attachment applied. Fig.2 is a side elevation of the same. Fig. 3 is a detail of thesupporting-w'heel. Fig. 4 is a detail of the slotted crank-arm, and Fig.5 is a longitudinal sectional detail of the seed-box.

Referring now more particularly to the drawii'igs, 1 represents a harrowof ordinary construction, having the cross-bars 2 provided with teeth 3and also having the levers 4 and lever-bars A represents the frame of myattachment, this frame consisting in the present instance of thecross-bar a supporting the bars a a, which are in turn connected also bythe bar a and of the bars a attached at one end to the cross-bar a; nearthe bars a and meeting at their other ends, thus forming a triangularinclosure. Of course the details of. construction of this frame can bevaried, and the seedbox B can be attached thereto in any convenientmanner; but I prefer to effect this by extending the bars a to beyondthe bar a, as shown, and fastening the box upon such extensions. Thisbox may be constructed in many ways but I prefer to employ that shown inwhich the bottom consists of two pieces I) I), each provided with asemicircular recess to form the opening I), which extends the length ofthe box, and each piece I) having a series of apertures Uitheseapertures being so placed that those in the upper half I) are out ofline with those in the lower half. A rod 0 fits loosely in the openingI) and has attached to it means for reciprocatin g it. Thus by reason ofthe apertures D and the longitudinal opening 1) this agitator causes adischarge of the seed.

Various ways can be employed for support ing the rear end of the frameand for reciprocating the rod 0. Preferably, however, a shaft d extendsbetween the bars (L3 a at a suitable distance from their point ofjuncture, and upon said shaft is mounted a wheel D, having thereon agear (Z. A shaft E is journaled upon the cross-bar a and a support esaid shaft having at its rear end a gear 6 in mesh with the gear d, andat its other end being connected with the rod (J, such connection beingeffected by reason of the crank e and the links a c 0 In order toregulate the amount of movement of the rod C at each reciprocation andthus in turn regulate the amount of feed, the crank-arm e is providedwith a slot 6 at any point along the length of which the bolt 0 or otherfastening upon the link a can be secured.

Preferably the crossbar a extends a short distance on each side of thebars a a, and these extensions are provided with a series of openings f,through which the clips F for attaching the frame to the harrow areinserted.

lever-rods 5 of the harrow, and the series of openings f permitattachment to harrows of various widths.

It will thus be seen that I have produced in a simple, light and durablestructure a seed distributing attachment which can be applied to anyharrow of ordinary construction. It is only necessary to attach the seedboX in some way upon the harrow, the rest of the attachment beingsupported by the wheel D, so that the seed can be sewn in advance of allof the barrow-teeth, after the passage of all of said teeth, or aftercertain of the teeth only have prepared the ground,leaving the remainingteeth to slightly cover the seed sown. The wheel I) not only supportsthe rear of the frame, but also transmits motion to the bar C, wherebythe seed is distributed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A harrow attachment comprising a frame, a seed distributer upon saidframe, means for removably attaching one end of the frame to These clipsare preferably passed under thethe harrow, and a support upon the framefor holding from the ground the portion unsupported by the harrow;substantially as described.

2. A harrow attachment comprising a frame, a seed distributer upon saidframe, means for removably attaching one end of the frame to the harrow,and a wheel upon said frame and supporting the portion of the frameunsupported by the harrow; substantially as described.

3. A harrow attachment comprising a frame, a seed distributer upon saidframe, a series of openings upon said frame, and means for connectingthe attachment to the harrow adjustable in said openings; substantiallyas described.

4. The combination with a harrow provided with lever bars, of a seeddistributer attached to said lever bars substantially as described.

5. An attachment for use with aharrow having lever bars thereon, saidattachment comprising a frame, a seed distributer upon said frame, andsecuring means upon said frame for engaging the lever bars;substantially as described.

6. An attachment for use with a harro w having lever bars thereon, saidattachment comprising a frame, a seed distributer upon said frame, andsecuring means upon said frame for engaging the lever bars, saidsecuring means being adjustable, whereby the attachment can be placedupon harrows of various sizes; substantially as described.

7. An attachment for use with harrows having lever bars, said attachmentcomprising a frame having a cross bar a provided with a set of openingsat its ends for extending over the lever bars upon the harrow, a seeddistribute]- upon said frame, and clips adapted to be passed under thelever bars adjustable in the openings; substantially as described.

8. A harrow attachment comprising a frame. a seed box upon said frame,said box being provided with an agitator, means for removably supportingone end of the frame upon the harrow, means for supporting the other endof the frame, and a connection between said last mentioned means and theagitator for operating the latter; substantially as described.

9. A harrow attachment comprising a fram e. a seed box upon said frame,said box being provided with an agitator, means for remov ablysupporting one end of the frame upon the harrow, a wheel upon the otherend .of the frame for supporting the same, and connections between saidwheel and the agitator for operating the latter; substantially asdescribed.

10. A harrow attachment comprising a seed box, means for discharging theseed from the box, and means for adj ustably supporting the box withrelation to the teeth upon the harrow, whereby the seed can bedischarged before the passage over the ground of any of the teeth, afterthe passage of all of the teeth, or after the passage of some of theteeth and before the passage of the others; substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
